Underdue faces life without the possibility of parole if convicted of killing Bobby Jones, 26, Victor Anderson, 25 and Keynon Hankins, 16, on the second-floor of 190 Delaware Ave. , where he went on Jan. 29, 2008. He was arrested the next day, police say, after giving a detailed three-page confession in which he said he “just lost control.”

Security is expected to be heightened in Albany County Court for Underdue, whose arraignment in City Court prompted a visible response from the victims friends and family.

Among the evidence at the disposal of Albany County prosecutors in his alleged statement to police. In it, Underdue said he murdered the three victims after a night of drinking French vodka and smoking pot.

“I guess I was getting mad and I got into a zone” he said, according to the statement. “I kept on getting madder and madder.”

The evidence against Underdue is expected to be strong. After giving the alleged confession, police say, Underdue actually hugged a detective.

The defense unsuccessfully tried to keep Underdue’s statement from the trial. The defendant’s lawyer has previously argued that DNA on the gun shows Underdue did not kill the victims.

The trial is before Judge Stephen Herrick. Assistant District Attorney David Rossi will handle the case for prosecutors. Attorney Lee Kindlon is representing Underdue, who is being held without bail.
